Motor oil, or lubricant, is derived from crude oil, a fossil fuel. Fossil fuels are a mixture of hydrocarbons formed from the remains of prehistoric organisms, such as animals, plants, and microplankton, that lived millions of years ago. Over time, the remains of these organisms were covered by layers of sand, silt, and rock, transforming under heat and pressure into what we now call crude oil or petroleum. Crude oil deposits have a unique composition and proportion of hydrocarbons, resulting in a range of densities. Once extracted, crude oil is separated into its individual hydrocarbon-based fuels and lubricants for industrial and transportation use.

What You'll Learn
Motor oil is a fossil fuel
The use of fossil fuels, including motor oil, has been important to human development, as they can be readily burned in the open atmosphere to produce heat. The wide-scale use of fossil fuels in steam engines enabled the Industrial Revolution, and the invention of the internal combustion engine increased the demand for gasoline and diesel oil, which are made from fossil fuels. Motor oil, in particular, is derived from crude oil and is used as a lubricant and fuel for vehicles. It is also used in plastics, cosmetics, and medicine.
While motor oil has been essential to human progress, its use comes with negative environmental consequences. The burning of fossil fuels releases CO2, accelerating climate change and contributing to air pollution, smog, and acid rain. Additionally, the harvesting, processing, and distribution of fossil fuels have further environmental impacts. For example, coal mining methods can negatively affect the environment, and oil drilling poses hazards to aquatic life.
To mitigate these negative effects, there has been a growing movement towards using alternative energy sources, such as renewable energy. Environmental regulations have also been implemented to limit emissions and protect natural environments. Despite these efforts, the burning and extraction of fossil fuels, including motor oil, continue to have significant impacts on the planet and human health.

Crude oil and petroleum
Petroleum products are fuels made from crude oil and the hydrocarbons contained in natural gas. Crude oil is typically transported by tanker ships, requiring the combustion of additional fossil fuels. After crude oil is removed from the ground, it is sent to a refinery where different parts of the crude oil are separated into usable petroleum products. A US 42-gallon barrel of crude oil yields about 45 gallons of petroleum products in US refineries due to refinery processing gain.
The use of petroleum dates back more than 2000 years to ancient China, where it was first discovered, extracted, and used in its raw state without refining. By the 4th century BCE, the Chinese were the first to record the use of petroleum as fuel. In the 7th century, petroleum was among the essential ingredients for Greek fire, an incendiary projectile weapon used by Byzantine Greeks. Crude oil was distilled by Persian chemists, and the streets of Baghdad were paved with tar derived from petroleum. In the 9th century, oil fields were exploited in the area around modern Baku, Azerbaijan, and the output of these wells was described by Marco Polo in the 13th century as hundreds of shiploads.
In the mid-19th century, various parts of the world saw oil well developments. In 1846, Russian Imperial engineers accidentally struck oil while hand-drilling with a primitive percussion rig in Bibi-Heybat, near Baku. In 1853, Ignacy Łukasiewicz discovered how to distill kerosene from seep crude oil and invented the modern kerosene lamp, hand-digging the first intentional well for commercial oil extraction in Poland. In 1857, a hand-dug well and refinery were established in Romania, and in 1859, the first steam-powered well was drilled in Titusville, Pennsylvania, kick-starting the mass production and rapid expansion of the global petroleum industry.

Natural gas from plankton
Fossil fuels, including coal, oil, and natural gas, are formed from the remains of organic matter produced by photosynthesis. While fossil fuels do not come from dinosaur bones, they are formed from the remains of ancient plants and animals, as well as microplanktons, that lived millions of years ago. Over time, the remains of these organisms were covered by layers of sand, silt, and rock, and transformed into fossil fuels due to heat and pressure.
Natural gas, specifically, is formed from the decomposition of dead plankton, including phytoplankton (algae), zooplankton, and other organic matter, in ancient oceans. As the organic matter sinks to the bottom of the ocean, it mixes with inorganic, clay-like materials from streams and rivers, creating an organic-rich mud that can only form in still water environments. This environment must be anoxic, with limited oxygen exposure, to prevent the organic matter from being decomposed by bacteria. The organic matter is then buried by sediment and becomes lithified, creating organic shale or sedimentary rock.
Geological changes in the Earth's crust bring these deposits closer to the surface, making them more accessible for extraction. Natural gas deposits are valuable resources that can be extracted through drilling and provide energy for various purposes, such as cooking, heating, lighting, and powering engines and vehicles. They are also used in the petrochemical industry and contribute to climate change through the release of CO2 when burned.
Plankton plays a crucial role in the formation of natural gas, and their decomposition over millions of years contributes to the creation of this fossil fuel that we utilize today. The process by which dead plankton transforms into natural gas involves a series of steps, from sinking to the ocean floor to undergoing lithification, ultimately resulting in the formation of the valuable energy source that we rely on for various industrial and domestic applications.

Oil drilling and extraction
Fossil fuels, including oil, have been important to human development because they can be easily burned in the open atmosphere to produce heat and energy. The wide-scale use of fossil fuels enabled the Industrial Revolution, and the invention of the internal combustion engine increased the demand for gasoline and diesel oil, which are made from fossil fuels.
Once the drilling is complete, the production stage begins. A perforating gun is lowered into the ground and fired into the rock layer, creating holes that connect the rock holding the oil and gas to the wellhead. Fracking fluid, which is mostly water and sand with some chemicals, is pumped at high pressure through these perforating holes, creating tiny cracks in the shale rock and freeing the oil and gas. This fluid is then recovered and recycled for use in other fracking operations.
After all the oil and gas have been extracted, the well is permanently plugged, and the land is restored to its previous state. This process can be dangerous, with a high number of work-related fatalities in the oil and gas extraction industry. Oil drilling and extraction can also have negative environmental impacts, including the risk of oil spills and the release of methane and carbon dioxide into the atmosphere, contributing to climate change.

Fossil fuels and the environment
Fossil fuels have been important to human development as they can be easily burned in the open atmosphere to produce heat. They have been used to generate energy for transportation, electricity, and industry. The three types of fossil fuels are coal, oil, and natural gas. These fuels are formed from the decomposition of organic matter, such as plants, algae, bacteria, and animals, that were buried and subjected to heat and pressure over millions of years.
The use of fossil fuels, however, has had a significant negative impact on the environment. The burning of these fuels releases large amounts of carbon dioxide, a greenhouse gas, into the atmosphere, contributing to global warming and climate change. In 2018, 89% of global CO2 emissions came from fossil fuels and industry. Oil, in particular, releases a significant amount of carbon when burned, accounting for about a third of the world's total carbon emissions. Additionally, the extraction and processing of fossil fuels can result in air and water pollution, including toxic nitrogen oxide emissions, and endanger aquatic life. Oil spills and leaks during extraction or transport can also devastate ocean ecosystems and pollute drinking water sources.
The environmental and health consequences of fossil fuel use have led to a growing movement towards alternative energy sources, such as renewable energy. The Paris Agreement of 2015 committed countries to reducing carbon emissions, and scientists advocate for a mass switch to renewable energy. While fossil fuel companies have promoted cleaner natural gas, it is still a fossil fuel contributing to carbon emissions.
Motor oil, or engine oil, is indeed derived from fossil fuels. It is a type of lubricant used in internal combustion engines to reduce friction and wear, and it is crucial for maintaining the performance and longevity of these engines. While motor oil is essential for vehicles, its production and use contribute to the environmental impacts associated with fossil fuels. The burning of motor oil releases greenhouse gases, and its extraction and refining processes can result in pollution and ecological damage.
